DESCRIPTION
The ADS1110 is a precision, continuously self−calibrating
Analog-to-Digital (A/D) converter with differential inputs and
up to 16 bits of resolution in a small SOT23-6 package. The
onboard 2.048V reference provides an input range of
±2.048V differentially. The ADS1110 uses an I2C-compatible
serial interface and operates from a single power supply
ranging from 2.7V to 5.5V.
The ADS1110 can perform conversions at rates of 15, 30, 60,
or 240 samples per second. The onboard programmable
gain amplifier (PGA), which offers gains of up to 8, allows
smaller signals to be measured with high resolution. In
single-conversion mode, the ADS1110 automatically powers
down after a conversion, greatly reducing current
consumption during idle periods.
The ADS1110 is designed for applications requiring
high-resolution measurement, where space and power
consumption are major considerations. Typical applications
include portable instrumentation, industrial process control,
and smart transmitters.
